M111 2.2 misfire thread :-/

[W124barr]

Hi everyone.

I have a 1994 W124 2.2 M111 and iv recently fitted a new loom, the car hasn't been ran in about 6 months so came to fire it up and its started but running very lumpy.

Whilst the car was in storage, it had been parked in a terrible place which has leaked water into the top of port 3 & 4 i removed the HT leads cleaned and dried them and replaced the plugs.

However still lumpy, i suspect there may be moisture trapped in the HT leads and have ordered some new ones to replace.

Im a bit out of touch with the old mercedes, so could damp in the HT leads cause the misfire? Im starting with this before going down the coil route etc, i know the loom is good as its brand new along with the coil lead
